Interpretive Summary: The Uniform Winter Barley Yield Nursery (UWBYN) is a cooperative effort of the USDA-ARS and various state Agricultural Experiment Stations to allow plant breeders to evaluate promising experimental cultivars for their agro- nomic performance in a wide variety of growing conditions. The choice of experimental design used to grow the nursery was made by the cooperator for each location and average performance values were submitted for inclusion in this report. Data reported from the various locations included yield, test weight, plant height, lodging, heading date, ripe date, winter- kill, leaf rust, barley yellow dwarf virus, stripe rust, powdery mildew, scald, and seedling reaction to several diseases. The Uniform Winter Barley Yield Nursery was grown at 16 stations in 14 states. Of 22 total entries, 9 were new entries in this year's nursery. The average yield over lines and stations was 69.3 bu/A with line averages ranging from 48.4 to 80.8 bu/A. PA649-406 was the top yielding experimental line, with nine other lines (including Wysor) yielding at levels not statistically different from this when averaged over all locations. The highest yielding location was Warsaw Virginia where the average of all entries was 109.3 bu/A. The best entry for test weight, when averaged over all locations, was SC860974 at 56.3 lb/bu. All other lines had average test weights that were statistically different this line.

Technical Abstract: The Uniform Winter Barley Yield Nursery was grown at 16 states. Of the 22 total entries, 9 were new entries in this year's nursery. The choice of experimental design used to grow the test was made by the cooperator at each location and mean performance values were submitted for inclusion in this report. The average yield over lines and stations was 69.3 by/A with averages ranging from 48.4 to 80.8 bu/A. PA8649-406 was the top yielding experimental line, with nine other lines (including Wysor) yielding at levels not statically different from this line, when averaged over all locations. The highest yielding location was Warsaw, Virginia where the average of all entries was 109.3 bu/A. The best entry for test weight, when averaged over all locations, was SC860974 at 56.3 lb/bu. All other lines had average test weights that were statistically different from this line.
